Inclusion criteria

* Female individuals aged 18-30 years * Voluntary agreement to participate in the study and approval of the online informed consent form For the bruxism group: * Self-reported teeth clenching and/or grinding behavior during wakefulness or sleep within the past 6 months * Presence of clinical findings supporting bruxism (e.g., tooth wear patterns, masseter/temporalis muscle tenderness) identified during a clinical examination conducted at the Faculty of Dentistry For the non-bruxism group: * No self-reported teeth clenching or grinding behavior * Absence of clinical findings supporting bruxism upon examination Bruxism classification will be performed in accordance with the current international consensus, based on self-report combined with clinical findings, within the framework of "probable bruxism" (Verhoeff et al., 2025).

Exclusion criteria

* Diagnosed temporomandibular joint (TMJ) dysfunction or significant jaw pain syndromes * History of major pelvic surgery; early postpartum period (\<1 year) or current pregnancy * Neurological disorders (e.g., multiple sclerosis, peripheral neuropathies) * Presence of active urogenital or colorectal infection/disease * Diagnosed pelvic floor pathologies (e.g., advanced pelvic organ prolapse, severe urinary/fecal incontinence) * Chronic use of opioids, anticholinergic agents, or muscle relaxants * Severe psychiatric disorders (e.g., diagnosed major depressive disorder, generalized anxiety disorder) * Receipt of any bruxism-related treatment within the past 6 months (e.g., occlusal splint therapy, botulinum toxin injections, intensive physiotherapy)

Design outcomes

Primary

MeasureTime frameDescription
Bruxism Assessment Section6 monthsSleep and awake bruxism will be evaluated according to the bruxism diagnostic criteria established by the American Academy of Sleep Medicine (AASM) in 2023. Bruxism-related pain will be subjectively assessed using the Visual Analog Scale (VAS). The Visual Analogue Scale (VAS) is a 10-cm used to measure pain intensity, where 0 represents "no pain" and 10 represents the "worst imaginable pain. Patients mark their pain level, which is measured in cm or mm to determine the score.
Jaw Function Assessment Section6 monthsJaw function will be evaluated using the Jaw Functional Limitation Scale-20 (JFLS-20). The Jaw Functional Limitation Scale-20 (JFLS-20) scores range from 0 to 200 (or 0-10 average per item), with higher scores indicating more severe jaw functional limitation. It measures 20 items across three constructs-mastication, vertical mobility, and verbal/emotional expression-using a 0-10 scale, with 0 meaning "no limitation" and 10 meaning "severe limitation
Pelvic Floor Assessment Section6 monthsPelvic floor symptoms will be assessed using the Pelvic Floor Distress Inventory-20 (PFDI-20) and the relevant items of the Pelvic Pain Impact Questionnaire. The Pelvic Floor Distress Inventory-20 (PFDI-20) is a questionnaire measuring the severity of pelvic floor dysfunction, with total scores ranging from 0 to 300 (0 = no distress, 300 = maximum distress). It includes three subscales-POPDI-6, UDI-6, and CRADI-8-each scored from 0 to 100, calculated by multiplying the mean of answered items (0-4) by 25

Secondary

MeasureTime frameDescription
Anxiety Assessment Section6 monthsAnxiety levels will be assessed using the State-Trait Anxiety Inventory (STAI - State Anxiety Scale). The State-Trait Anxiety Inventory (STAI-S) assesses temporary, immediate, or situation-specific anxiety using a 20-item self-report questionnaire with 4-point Likert-type responses. Scores range from 20 to 80, with higher scores indicating higher levels of anxiety. A cutoff of 39-40 is often used for detecting clinically significant symptoms.
